Title: Manufacture of polyhydroxy compounds
IPC: C07C29/38
Filed: 1946-08-14
Abstract: Polyhydroxy compounds are produced by reacting a mixture of formaldehyde, carbon monoxide and hydrogen, the formaldehyde being initially present, at a pressure of not less than 200 atmospheres and at a temperature of from 80 to 300 DEG  C. in the presence of a hydrogenating catalyst.  Instead of formaldehyde compounds yielding it under the reaction conditions may be used, e.g. paraformaldehyde, reactive formals, trioxane, and N-methylol derivatives.  The reaction products may be further treated with hydrogen to obtain increased yields of hydroxy compounds boiling in the range of the lower glycols, and glycerine.  This subsequent hydrogenation may be conducted in the presence of a hydrogenation catalyst, e.g. copper chromite at superatmospheric pressure at a temperature of about 100 DEG  to 300 DEG  C.  Specified hydrogenating catalysts for the main reaction are nickel, cobalt, manganese, iron, chromium, copper, platinum, molybdenum, palladium, zinc, cadmium, ruthenium and compounds thereof or combinations of these materials with each other or with inert supports, e.g. kieselguhr, pumice, or with promoters such as thoria and manganese.  Preferred catalysts are cobalt-containing catalysts such as metallic cobalt, reduced sintered cobalt oxide, cobalt carbonyl and salts of cobalt.  Preferred temperatures are 100 DEG  to 200 DEG  C. and pressures of 200 to 1500 atmospheres are preferred.  The reaction may be effected in an inert reaction medium, e.g. an aliphatic ether or ester.  In examples: (1) a mixture of paraformaldehyde, methyl formate and reduced sintered cobalt oxide is heated in a silver-lined shaker tube under a pressure of 500 to 700 atmospheres of a mixture of carbon monoxide and hydrogen, distillation of the resulting mixture yields a mixture of polyhydroxy compounds; (2) reaction is effected as in (1) but a pressure of 460 to 750 atmospheres is employed, the resulting product is freed from methyl formate and then hydrogenated in methanol solution in the presence of copper chromite at a temperature of 230 DEG  C. under a pressure of 745 to 750 atmospheres. Distillation of the product yields fractions containing ethylene glycol and glycerol respectively; (3) a mixture of trioxane, distilled water and reduced sintered cobalt oxide are heated under a pressure of 550 to 640 atmospheres of a gas containing carbon monoxide and hydrogen and the resulting product distilled yielding polyhydroxy compounds; (4) a mixture of paraformaldehyde, methyl formate, and reduced sintered cobalt oxide is heated under pressure and a mixture of carbon monoxide and hydrogen is then injected and the heating continued under a pressure of 445 to 735 atmospheres.  Distillation of the product gives a syrupy residue containing polyhydroxy compounds and unspecified oxygenated compounds.  The molecular ratio of carbon monoxide to hydrogen used is preferably from 4 : 1 to 1 : 10 and in the examples about 1.5 to 2 moles of carbon monoxide is initially present per mole of formaldehyde.

Title: Improvements in or relating to the manufacture of electrical devices having a sealedevacuated envelope
IPC: H01J9/38
Filed: 1952-10-01
Abstract: 744,758. Discharge apparatus. GENERAL ELECTRIC CO., Ltd., BREADNER, R. L., and SIMMS, C. H. Sept. 23, 1953 [Oct. 1, 1952], No. 24636/52. Class 39 (1). A device such as a discharge lamp 7 is exhausted through an aperture 9 which is brought into register with an aperture 11 in the wall of an exhausting chamber, and afterwards sealed by applying a closure or plug from within the chamber to the aperture 9. In the embodiment shown, an oven 3 surrounds the lamp 7, which abuts against the chamber wall with an intervening gasket 12, the two apertures 9 and 11 being in alignment. The aperture 9 is stepped to form a seating for a closure washer 10 held on the end of a cranked movable rod 27, 33. When it is required to seal up the lamp, the cranked rod is moved downwards against a retracting spring by means of a solenoid 31 and armature 30. The washer 10 is of or coated with a thermoplastic such as polymerized ethylene, or a resin or glass solder, which softens and fuses in contact with the heated lamp base 8. Alternatively a greased washer of non-porous rubber may be used. The part 33 may be arranged as a magazine of washers 10 for application to several lamps successively. Prior to sealing, a predetermined quantity of mercury may be introduced into the lamp from a reservoir supply 16. A rod 17, actuated in a similar way to rod 27, has a recess 18 which, as the rod moves downwards, transfers a globule of mercury from the reservoir into the lower part of the exhausting chamber. Here it falls into a funnel 24, which is so shaped and adjusted as to guide it through aperture 9 into the lamp. The funnel is pivoted so that it is temporarily pushed out of the way by a finger 34 on the crank 33 as the latter descends for the sealing operation. The lamp is accurately positioned by the engagement of the base terminals (not shown) with locating springs (not shown) attached to the periphery of aperture 11, and which also act as conductors for heating the lamp electrode during processing. Specification 744,751, [Group XXXVI], is referred to.

Filed: 1944-12-11
Abstract: Pyrazolone derivatives of the probable general formula <FORM:0599919/IV/1> wherein R represents an alkyl or heterocyclic radical and R1 hydrogen or an acyl group, are manufactured by heating together, if necessary in the presence of alkali (e.g. sodium methylate or ethylate), an alkylhydrazine or a heterocyclic hydrazine and a b -alkoxy-b -iminopropionic ester (i.e. the iminoether derivative of a cyanoacetic ester), or by heating together a 3- or a 4-pyridylhydrazine and a cyanoacetic ester, and in either case, if desired, acylating the product by warming it with two molecular proportions of an acyl chloride to form an acylamino-acyloxy-pyrazole and then hydrolysing the acyloxy group by adding water to a warm solution of the pyrazole in an organic solvent.  The products may be employed as colour couplers in colour photographic development (see Group XX).  In examples, the imino ethyl ether of ethyl cyanoacetate is condensed with 2-benzthiazolyl-, 2-, 3- and 4-pyridyl-, 2-quinolyl- and 2-benzoxazolyl-hydrazine to produce the corresponding 1-substituted 3-amino-5-pyrazolones, in some cases with intermediate isolation of the corresponding b -(substituted-hydrazino)-b -iminopropionic ester.  In a further example, 1-(21-quinolyl)-3-amino-5-pyrazolone is acylated with 2 molecular proportions of benzoyl chloride and the product partially hydrolysed to 1 - (21 - quinolyl) - 3 - benzoylamino - 5 - pyrazolone. Specifications 427,516, 427,520, 440,032, 440,089, 447,092, [all in Group XX], 478,990, 507,841, 524,154, 524,554, 524,555, 541,589, [all in Group XX], 547,064 and 553,506 are referred to.  Azo dyestuffs are manufactured by coupling a diazo compound with a pyrazolone of the general formula above.
